ABSTRACTOCE-0326814 / OCE-0327188The SOLAS initiative has as its goal to quantify biogeochemical-physical atmosphere-ocean interactions and determine how this coupled system affects climate and environmental change. One of the key objectives is accurate quantification of air-sea gas transfer rates. The lack of field observations leaves large gaps in our understanding of gas fluxes, and the most urgent region requiring observations is the Southern Oceans. Models have shown that this region has a large potential effect on the ocean carbon sink over the next 60 years. In this project researchers at the Woods Hole Oceanographic Institution and the Rosenstiel School of Marine and Atmospheric Sciences (University of Miami) will participate in the SOLAS-ANZ (Surface Ocean Lower Atmosphere Study - Australia/ New Zealand) gas transfer experiment in the Southern Ocean in November, 2003. The SOLAS- ANZ cruise will be a bio-perturbation experiment involving the addition of iron to stimulate a phytoplankton bloom. The corresponding modification to the gas transfer will be quantified with the dual tracer technique, as well as micrometeorological methods. The Woods Hole and RSMAS team involvement in the expedition will be through the deployment of the SkinDeEP profiler and the M-AERI spectroradiometer. SkinDeEP is equipped with high-resolution temperature and conductivity sensors to investigate microstructure from a depth of 10 m to the surface. The team will extend the measurement capability of SkinDeEP with the addition of oxygen and PAR sensors. The M-AERI spectroradiometer provides highly accurate ocean skin temperature measurements. Participation in this bio-perturbation experiment will allow them to obtain estimates of the influence of temperature on gas fluxes. The high-resolution oxygen profiles will allow quantification of biological production and consumption in the surface layer. The PAR measurements will also provide an indicator of biological activity through the absorption of light. These measurements will be conducted both inside and outside the fertilized patch. The international collaboration established through this project will allow the transfer of knowledge between researchers from the US and New Zealand. The research team expects to make daily updates of the cruise available on a web site, in a similar fashion to the recently NSF-funded SOFeX experiment, thereby allowing the public insight into the daily activities of an oceanographic field experiment.

Abstractoce-0326814 / OCE-0327188 SOLAS倡议的目标是量化生物地球化学大气 - 海洋互动，并确定该耦合系统如何影响气候和环境变化。 关键目标之一是准确量化空气气体传输速率。 缺乏现场观测在我们对气体通量的理解中留下了很大的差距，而需要观察的最紧迫的地区是南大洋。 模型表明，该区域对未来60年的海洋碳汇具有很大的潜在影响。在这个项目中，伍兹霍尔海洋学机构和罗森斯蒂尔海洋与大气科学学院（迈阿密大学）将参加2003年11月在南部海洋的Solas-Anz（Surface Oania sistran-anz sopera nower Apenterere研究 - 澳大利亚/新西兰）的天然气转移实验。 对气体转移的相应修改将通过双示踪技术以及微量标学方法来量化。 Woods Hole和RSMAS团队参与探险将是通过Skindeep Profiler和M-Aeri Spectroradiometer的部署。 Skindeep配备了高分辨率温度和电导率传感器，可研究从10 m到表面的深度的微观结构。 该团队将通过添加氧气和PAR传感器来扩展Skindeep的测量能力。 M-AERI光谱仪可提供高度准确的海洋皮肤温度测量值。参与此生物扰动实验将使他们能够获得温度对气体通量影响的估计。 高分辨率的氧轮廓将允许量化表面层中的生物产生和消耗。 PAR测量还将通过吸收光提供生物活性的指标。 这些测量将在受精的斑块内部和外部进行。通过该项目建立的国际合作将允许美国和新西兰研究人员之间的知识转移。 研究小组希望以与最近由NSF资助的SOFEX实验相似的方式进行每日可用的巡游更新，从而使公众了解海洋学现场实验的日常活动。
